Walmart has
Mobile One
Mobile One Extended Performance 15,000 mile
Mobil One Annual Protection
these are all full synthetic and all are available in 5-30
I have always just grabbed the normal Mobil One when it comes time to change the oil - is there any reason why one of the others would be a better choice - they are all right around the same price plus or minus so I figured why not ask. I would still change my oil every 5,000 miles or less so I dont care about lasting 15,000 or 20,000 miles, but if one offers better protection than the others I would like to know
Thanks
